Azistern 3065

Fuel saving harbour tug design

Offshore Ship Designers has built on lessons learnt in its Green Tug project to launch a new standard design for a fuel saving and low wake harbour tug. The Azistern 3065 tug will deliver 65 - 70 tonnes bollard pull from a 31 m loa hull powered by two 1,950 kW diesel engines driving twin azimuthing stern thrusters. It will be around 15 per cent more fuel efficient than comparable modern tug designs, due to the optimised hull shape.

The Azistern 3065 is the first of a family of designs which OSD will launch for different fuel efficient tug sizes. The hulls have a hard chine form which has undergone extensive tank testing to optimise energy saving during transit. It also results in a very low wash, which is important in a crowded harbour.

A conventional machinery package has been specified to ensure the vessel is simple to build and maintain in shipyards around the world, but close attention has been paid to ensuring the design is state of the art. The uncluttered decks, twin forward and aft winches and good visibility ensure ease of handling for the three man crew.

In addition to the main engines, which will give a maximum transit speed of 13 knots and BP up to 70 tonnes ahead and 65 astern, the Azistern has a 300 KW bow thruster. The compact hull has a gross tonnage of 423 gt and a design operating draft of 5.40 m.
